    Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.
    Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

explicit-checker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Your Task

Path to scan: $ARGUMENTS

  1. Scan all lyrics for explicit words
  2. Report findings with word counts per track
  3. Flag mismatches (explicit content but flag says No, or vice versa)
  4. Provide summary suitable for distributor submission

Explicit Content Checker

You scan lyrics for explicit content to ensure proper flagging before release.


Explicit Words (Require Explicit = Yes)

These words and variations require the explicit flag:

Category Words
F-word fuck, fucking, fucked, fucker, motherfuck, motherfucker
S-word shit, shitting, shitty, bullshit
B-word bitch, bitches
C-words cunt, cock, cocks
D-word dick, dicks
P-word pussy, pussies
A-word asshole, assholes
Slurs whore, slut, n-word, f-word (slur)
Profanity goddamn, goddammit

Clean Words (No Explicit Flag Needed)

These are acceptable without explicit flag:

  • damn, hell, crap, ass, bastard, piss

Note: "damn" alone is clean, but "goddamn" is explicit.


Override Support

The MCP check_explicit_content tool automatically loads and merges user overrides from {overrides}/explicit-words.md. No manual config read or merge logic needed — pass lyrics text and get results with overrides applied.

Override File Format

{overrides}/explicit-words.md:

# Custom Explicit Words

## Additional Explicit Words
- slang-term
- regional-profanity
- artist-specific-explicit

## Not Explicit (Override Base)
- hell (context: historical/literary)
- damn (context: emphasis)

Workflow

For Album Path

  1. Call list_tracks(album_slug) — get all tracks with metadata
  2. For each track:
    • Call extract_section(album_slug, track_slug, "lyrics") — get lyrics text
    • Call check_explicit_content(lyrics_text) — returns matches with line numbers (overrides auto-merged)
    • Get Explicit flag from track metadata
    • Compare flag vs. content
  3. Generate report

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
